# Hunyuan 3D v2 Mini

THREE\_DFeaturedtencent-hunyuan3d-v2-mini

**Hunyuan 3D v2 Mini** is a lightweight, efficient version of [Tencent’s](https://github.com/Tencent/Hunyuan3D-2) impressive Hunyuan 3D model. It is optimized to run on less powerful hardware while still delivering good quality 3D assets, making it highly accessible for hobbyists, students, and developers. For the open-source community, this ‘Mini’ version provides an excellent entry point for experimenting with 3D generation without requiring high-end computational resources.

Best for

Lightweight open-source 3D for modest hardware, Approachable entry point for 3D experimentation

## Parameters

### Path Parameters

**workspace\_id**

required

_Workspace Id_

Id of the workspace that owns the resource.

string format: uuid

Id of the workspace that owns the resource.

### Query Parameters

**session\_name**

_Session Name_

Organize this run under a named session. A new session is created if none matches.

string

nullable

Organize this run under a named session. A new session is created if none matches.

### Header Parameters

**Idempotency-Key**

string

<= 255 characters

Opaque key making a retry of this request return the first result. A 2xx response is replayed for 24 hours with `Idempotent-Replayed: true`. A 4xx releases the key. A 5xx, or a request still running, holds the key for 120 seconds, during which a retry gets 409; after that a retry executes again. The key covers the method, path, query, and byte-identical body it was first used with; reusing it for a different request is rejected with 422\. Protection is best effort: if the key store is unavailable, or a record is lost early, a retry can execute again even after an earlier 409\. See the Idempotency section of the API description.

## Request Bodyrequired

_Hunyuan 3D v2 Mini_object

**seed**

_Seed_

The starting point for the model’s randomness. The same seed and settings give the same result.

_Advanced field._

integer

nullable

**guidance\_scale**

_Guidance scale_

How closely the result follows the prompt. Lower gives the model more freedom.

_Advanced field._

number

default: 7.5 <= 20 multiple of 0.5

**inference\_steps**

_Inference steps_

How many refinement passes the model makes. More add detail and take longer.

_Advanced field._

integer

default: 50 \>= 1 <= 50 multiple of 1

**include\_textures**

_Generate textures_

Paint colour onto the mesh. Off returns bare geometry.

boolean

default: true

**guidance\_file\_init\_image**

required

_Source image_

The image the 3D model is built from

\>= 1 items

_InferenceFormFileRef_

A single guidance/reference file supplied to a `reference_image_list` field.
